Application filed September 3, 1.921. Serial No. 498,218.

T0 @ZZ ywhom t may con-ccm: I

Be it knoivn that lY` Maurin C. Bniisino, residing at Illinois. have invented certain neiv and use- ,'ul Improvements in Cover Supports tor Phonographs, ot which the followingis a specification. y

'Heretotore it'lias been customary to provide phonograph cabinets and also other cabin'etsivith cover supports which are 'tastenedivithin the cabinet to theside Wall thereof and connected with the side ot' the cover. but this construction has certain dis advantages among which may be mentioned the difficulty oit securely fastening' the device to the comparatively thin veneer stock ot Which the cabinet is made without detacing theoutside iinish on the Wall ot the cabinet. and also the tact that a side support has a tendency to malte the cover tvvist or Warp in time and then torni an imperteot closure when the cover is closed.

My present invention has toi' its object to avoid these and other disadvantages ot cover supports heretofore lin-own and to pro` vide'a cover support adapted to be mounted as a complete unit on the underside oi' the motor board, 'sometimes called tl e top board. ot `the cabinet. and connected to thc cover at the back and substantially midway between the sides thereof whereby the device may' be securely fastened in piace in the cabiiietby strong; and substantial fastening means and Without liability ot detacine the outside 'linish otl the cabinet and also Wheren by the lstrain incident to raising' and lowering the cover are instead oi? to the side. and distributed `with relation to the cover hinge' to eliminate the liability ot the cover twisting or warping byk reason et the cover support.

f Further objects ot provide a-'strong and substantial cover supvfp'ort of simplev and compact constructiony which can be easily adjusted andtastened in place and which can. be readjusted as occasion may require Without access to the enclosed parts ot the cabinet: to provide a comparatively short and stronger to mount thespringl so that it will be substantially parallel with the lift bar and the sides of the cabinet when the cover is closed; to'support and guide the operative parts ot the device so that they `Will `always 'operate State ot spring: f f than has been generally used heretotoie and applied to the back thereof, i

the invention are `to n which has an opening jlever and is sufficiently ing in the lever, and

as `desired and not out ot order by Wear or otherwise; to support the device firmly and rigidly in operative position; and to enable the device to be easily adjusted to motor boards ot diderent thickness.

, The invention has other objects in vienv which will be pointed out hereinatter iii the detailed ydescription ot a selected eiiibodi` ment thereof as illustrated in the aecompanying drawings in which.

VReferring to the drawings.. 'T indicates the body ot a phonograph cabinet to ivhicli the cover 8 is `attached by the usual hinge 9. i supporting plate is provided at the top thereof with a {iange 10 adapted to en- `trage the underside ot the motoi` board lt and bolts l2 passing through the motor board threadedly engage the 'Flange l0 and securely 'Fasten the supporting' plate to the motor board in upright position. A tacinp; plate 13 is fastened to the top oit'the motor board by the bolt-s l2. The supporting` plateis preferablyv stamped itroin sheet metal and an ear let is. struck up therefrom to provide a support't'or the bell crank lever i5. rllhis leve/ruis` pivotally mounted on the ear 1 4 of vthe supporting plate and the construction of this pivot is more clearly yshovvii in Fig. 5. The Lear 14 is indented at 11i to torni an enlargedvrounded bearingtor the lever l5 i i lo to receive said A Washerl'is arranged on the indented or 'cup shapedto tit `over thc indented port-ion llt of the earwhioh projects through the openthe parts are secured a rivet 17. This construction provides a large and efficient bearing 'tor the bell crank lever which will not wear loose duringthe ordinary lite ot' a cover support.

together by of a spring 18 is engaged With and the other end oi the spring is engaged with a hook 20 on the adjusting plate 2l.. A. screw bolt :l2 is threadedly engaged with a iiange 2? on the upper end of the adjusting plate and this bolt projects upward through the lange i0 oi" the supporting plate and tlnough the motor board and the facing plate Til. The bolt is provided. with a groove 2li to engage a slot 25 in the liange l0 of the supporting plate whereby the bolt is held against end-wise movementrelative to the supporting plate and is always maintained with its upper end projecting sutliciently above the tacing plate to receive a tool for turning the bolt and adjusting t-he ad'usting plate 2l for varying the tension o the spring rlhe upper end of the adjustingv plate is located in front of the supporting plate and the adjusting plate projects through the opening 9 in the supporting plate made by striking up the ear la and its lower end projects laterally at 2l. and then vtorwardly at 2l and is provided with a hook 20. e. lug 21 is bent laterally from the end 2. oit the adjusting plate to engage the supporting plate and lugs 26 and 26 are also provided on the supporting plate to form guides for the adjusting plate and to securely maintain it in proper relation to the supporting plate.

rlhe other arm 27 of the bell crank lever is connected to the lower section 28 of .a lift bar 29 and this connection is substantially in the form of a swivel to accommodate the oscillating movement of the lift bar relative to the bell crank lever. rlhe end of the arm 27 oi the bell cranlrlever is indented or cup shaped at 27 and the lower end of the litt bar section 28 is correspondingly indented or cup sha )ed at 28 so that these indented or cup shaped parts will lit one within the other and when secured together with a washer 8O and a rivet 30 the connection will be in the nature of a ball and socket joint to form a suiicient swivel to enable the lift bar 29 to oscillate in a plane normal to the plane of operation of the arm 27 of the bell crank lever. The section 28 is adjustably secured to the main section 29 of the lift bar by means of a bolt 3l which passes slot 33. in the section. 28 and threadedlyengages one of a plurality of openings 31 in the main section 29 of the-litt bar. This adjustment enables the lift bar to be shortened or lengthened as required to properly position the device in the cabinet. The upper end of the lift bar is bent forwardly at 2,9

and is pivoted at 32 to a bracket 38 which' is :fastened to the cover 8 at the back behind. the tone arm 33 and substantially midway between the sides of the cover. The lift bar projects upward through a slot ll in the motor board and through a corresponding slot 13 in the facing plate and the edges 13" of the facing plate are turned downwardly throughl a l to 'forni a neat finish. This construction also strengthens the facing plate in. the stamping operation by which it is formed andL helps to prevent distortion thereof.

Y The arm 27 of the bell crank lever is providedwith a lug 3a which. engages a flange l0 on the supporting` plato to guide the arm in its movement and a stop 35 is provided on the supporting` plate to positively limit the upward movement of the arm 27. A transverse bolt 36 is threadedly mounted in the adjusting plate to engage the side wall 37' `of the cabinet and the inner end of this bolt islrerfed to receive a tool whereby it can be adjusted to make proper engagement with the Awal 3T and form a guide or spacer 'tor maintaining the cover support in upright position parallel with said wall.

My invention provides a strong and sub` stantial but simple and compact spring device for holding the cover of a cabinet in closed position and for lifting the cover under slight pressure and holding it in elevated position. The construction is such that the spring is almost parallel with the lift bar when the cover is in closed position so that the cover will be held snugly against the body of the cabinet to form an eiiicient closure, and with a slight lifting pressure on i the cover the spring quickly throws the bell crank lever and lifts the cover to its desired elevated position. The device can be installed in a cabinet very easily and quickly as a unit and after once being adjusted to the cal. inet it will require no further attention. It vocasion should arisey for adjusting the spring after the device is installed it can be easily adjusted without entering the enclosed part oi the cabinet by turning the screw 22. The device can be made in standard sizes and iised on cabinets which vary considerably in structure because the adjustments are capable of accommodating motor boards otdii lerent thickness and a great variety of prothe selected. embodiment in the accompany-` ing drawings and herein described,- I am aware that changes may be required to adapt the device to ciiferent conditions and Itherefore reserve the right to make all such changes in the device as fairly fall within the scope oi? the accompanying claim` l l claim: d n l..
